Qiao Chenghuan traveled through time and became a foolish girl who was defrauded of all her family property by her cousin, and was sold to the Zhang family to celebrate her 70-year-old husband. On the night he entered the house, he mistakenly climbed into the bed of Zhang Yanli, the third young master who was sick and weak. As a result, the old master froze to death and the young master accidentally drank poisonous tea and died. She was drugged and thrown into a mass grave, but was rescued by Zhang Yanli. After recovering her memory, she killed her cousin, took her family to Qingzhou, and started selling tofu from scratch. Three years later, Zhang Yanli came to the door and took his son to pursue his wife. After returning to Beijing, the husband and wife teamed up to fight against the sister-in-law, the noble daughter, and the powerful. Qiao Chenghuan used her wisdom to establish the national store "Chenghuanji" and became the richest female businessman in the Great Zhou Dynasty. From mass graves to golden genealogy books, she spent her life proving that women can live a light life by themselves.
